I lost a diamond out of a ring yesterday :(
It wasn't my wedding ring or anything, but its super annoying just the same! They're expensive little buggers (please forgive the australian-ism in the use of the word "bugger") to replace.

Its a dress ring I have, and the other reason its so annoying is that it only has 7 stones in it, sort of like this, but a lot plainer, so the missing stones are more obvious (to me anyway?)
